Answer:
8684.2 kg/m³
Explanation:
Tension in the rope as a result of the weight = 8.86 N
Tension in the rope when submerge in water = 7.84
upthrust = 8.86 - 7.84 =1.02 N = mass of water displaced × acceleration due to gravity
Mass of water displaced = 1.02 / 9.81 = 0.104 kg
density of water = mass of water / volume of water
make volume subject of the formula
volume of water displaced = mass / density ( 1000) = 0.104 / 1000 = 0.000104 m³
volume of the object = volume of water displaced
density of the object = mass of the object / volume of the object = (8.86 / 9.81) / 0.000104 = 0.9032 / 0.000104 = 8684.2 kg/m³
Answer:
Scalar quantity
Vector quantity
Explanation:
A scalar quantity is a quantity that is fully described by magnitude alone. Examples include; mass, temperature etc
A vector quantity is described by both magnitude and direction. E.g force, weight etc
Energy can only be converted from one form to another
eg kinetic energy is converted to heat energy
Answer:
1) We can estimate the age of the earth
2) we can calculate the speed of anything
3) we can also calculate gravity, e.t.c.
Explanation:
I could give you more just ask
<span>Gravitational force is equal to 6 kg * 9.81 m/s^2 = 58.86 N. If air resistance is 15 n up, the magniture is 43.86 N downward.</span>
